[nanoPost] Nanostructures for LEDs

Company USA

The company are developing core technology, which is based on a proprietary class of inorganic nanostructures, to engineer and integrate the physical, functional and performance characteristics of nanostructures for the purpose of creating products.

Unlike traditional materials which are used to fabricate devices, each nanostructure can incorporate device functionality. These nanostructures, which can be made with features as small as a few nanometers, are synthesized atom by atom in a controlled chemical environment, creating precisely defined functional nanostructures. To design products for different application areas, our nanostructure fabrication process enables us to define and control many of the important chemical and physical parameters of our nanostructures, such as composition, shape, size and surface chemistry.

Composition: Our core technology allows us to fabricate nanostructures from one or more inorganic materials, including silicon, silicon germanium, cadmium selenide, gallium arsenide, gallium nitride and indium phosphide. Different inorganic materials can manifest different properties or perform different functions. For example, traditional integrated circuits are made from silicon, while light emitting diodes, or LEDs, are often made from gallium nitride. We can also incorporate two or more materials into each individual nanostructure, forming functional interfaces between the different materials that can provide unique electrical, optoelectronic or physical properties. Whether we are developing a solar cell, an LED or a memory device, the composition of the nanostructures can be selected to suit the application.

Size: Our core technology allows us to control the size of the nanostructures. While the composition of a nanostructure largely defines its overall function, we can adjust the desired functional properties by controlling the size of the nanostructure. This feature allows us to further change the performance characteristics of our products in a way that is not possible using traditional technology. For example, when using a nanostructure to form a light emitting structure, we can tailor the size of the nanostructure to select the precise color of the emitted light.

Shape: We can form nanostructures in a variety of shapes, including spheres, rods and wires, as well as more complex shapes. By controlling the shape, we can create additional functionality in our individual nanostructures and increase their performance, as well as, we believe, reduce the manufacturing complexity and cost of the product

Surface chemistry: While functionality results from the nanostructures’ composition, size and shape, processability arises from the material filling the space between individual nanostructures. The interface between the nanostructures and the filling materials is formed through a surface chemistry that acts as a physical and functional connection between the nanostructures and the other components in the end user product. By controlling the surface chemistry independent of the composition, size and shape of the nanostructures, we can separately define and optimize functional and manufacturing characteristics
